Robust Functional Regression via FPCA, Copula-Scale Design, and Multivariate Bernstein Smoothing

We introduce a robust nonparametric regression framework for functional covariates that combines functional principal component analysis (FPCA), marginal copula-scale normalization, bounded-score M-estimation, and multivariate Bernstein smoothing. The proposed procedure reduces the infinite-dimensional functional predi...
